Instead of open-coding the creation and +removal of these files (and getting it wrong btw), it's a better idea to +let the driver core handle all of this logic for us. + +So add a new field to the pci driver structure, **groups, that allows +pci drivers to specify an attribute group list it wishes to have created +when it is registered with the driver core. + +Big bonus is now the driver doesn't race with userspace when the sysfs +files are created vs. when the kobject is announced, so any script/tool +that actually wanted to use these files will not have to poll waiting +for them to show up. + +Cc: Faisal Latif <faisal.latif@intel.com> +Cc: Doug Ledford <dledford@redhat.com> +Cc: Sean Hefty <sean.hefty@intel.com> +Cc: Hal Rosenstock <hal.rosenstock@gmail.com> +Cc: Bjorn Helgaas <bhelgaas@google.com> +Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> + --- drivers/infiniband/hw/nes/nes.c | 69 +++++++++++++--------------------------- drivers/pci/pci-driver.c | 1 |
